One equation useful for the simplest type of these circuit components is permittivity times area all divided by distance. The SI unit of these components is defined in coulombs per volt. In parallel, the measure of the effectiveness of these components adds; in series, you must take the sum of the reciprocals of the individual measures. The most basic types of these circuit components are made up of two parallel plates. For 10 points, name these
